A protocol for the synthesis of a new family of spiropyran derivatives is described. A 5‐formylated indoline intermediate ( 5 ) was achieved for the first time, which was the key intermediate for constructing the spiropyran derivatives with vinylene linker. Five 5′‐functionalized indolinospiropyrans ( 11 – 15 ) were obtained by utilizing vinylene unit as a linkage between the photochromic spiropyran fragment and the ferrocene or triphenylamine donor.
